Error while extracting layout.

and by the way I am using cadence 5.0.33.500.3.41

I would expect there would be some more detailed errors shown - probably above this. That one error message reveals nothing!

Andrew.

I am sorry about that andrew. Yes there were other errors. The following is the grep from log file.

Well, that suggests two things:

1. Your tech file doesn't match the rule file, since there are warnings about the layer purpose pairs being missing.
2. It is trying to attach parasitics to a device, which has not been extracted. Perhaps you have to turn on some switch to extract the
devices found with cp1nwC as the recognition layer.

You may be able to look through the Diva rules file to see if cp1nwC is being used as part of an extractDevice() type statement.

However, the simplest thing is probably to ask whoever supplied the Design Kit for support. Have you read the documentation that comes with the design kit? (I assume there is some).

Regards,

Andrew.
